I noticed a bubble on my inner side left cheek and it popped... and it was blood what can it mean?

The Jets will win the superbowl?

Chances are that it was a clogged saliva duct that got infected and burst. Kind of like a sit on the inside of your mouth. So long as the bleeding has stopped you should be fine. If you're worried about it than see a doctor.
